Mathematics
1 answer:
SIZIF [17.4K]3 years ago
4 0

Answer:

<h2>YES</h2>

Step-by-step explanation:

If the number is rational, I can write it as a fraction in which the numerator and denominator are integers (denominator other than 0).

3.\underbrace{222222}_{6}=\dfrac{3222222}{1\underbrace{000000}_6}-\bold{RATIONAL}

If is repeating:

x=3.2222....       <em>multiply both sides by 10</em>

10x=32.2222...      <em>    make the difference 10x - x</em>

10x-x=32.2222...-3.2222...

9x=29             <em>divide both sides by 9</em>

x=\dfrac{29}{9}-\bold{RATIONAL}

Need help with these two questions linear relations.
wel

Answer:

b. y = -7x + 4

   1.    y = -7(-5)+ 4 = 35+4= 39

   2. -24= -7x + 4

    -28 = -7x

       4 = x

    3. y = -7(0)+4= 4

    4. 0 = -7x+4

        -4= -7x

         4/7 = x

c. 3y - 5x = 15

 1. 3y - 5(6)

    3y-30=15

    3y=45

      y = 15

   2. 3(-10)-5x=15

        -30-5x=15

         -5x = 45

            x = -9

    3. 3y-5(0)=15

        3y=15

         y=5

    4. 3(0)-5x=15

         0-5x=15

          -5x=15

           x=-3

The rectangle has an area of x to the second power plus 13x + 36 sq.Meters and a length of x + 9 meters. What expression represe
elena-s [515]

Answer: the expression for the width is x + 4

Step-by-step explanation:

The area of the rectangle is expressed as

Area = x² + 13x + 36 square meters.

The length is expressed as

L = x + 9 meters

To determine the expression for the width of the rectangle, we would factorize the expression for the area. Hence

x² + 13x + 36 = 0

We would find two numbers such that their sum or difference is 13x and their product is 36x². The two numbers are 9x and 4x. Therefore,

x² + 9x + 4x + 36 = 0

x(x + 9) + 4(x + 9) = 0

(x + 4)(x + 9)

Therefore, the expression that represents the width of the rectangle is x + 4
